>Those shitty books could have easily been half their respective lengths but I guess when you're famous you don't have to bother with the editorial process.
Keep moving goalposts, friend. What you said was that nothing happened, not that it could have been condensed. Of course, it can fucking be revised, condensed, and ultimately improved. Anything can.
Are you seriously comparing Martin to Rothfuss? Tell me, in what ways is the main narrative furthered In the Name of the Wind? Bad guys kill his family, they're mentioned a few more times in the first quarter, and then it ends on a cliffhanger just as he's about to learn more, some 500p later. Yeah, that totally sounds like ASoIaF.
And what the fuck kind of nonsense argument is that about LotR? Apart from the fact that they're both considered fantasy by normies, there's nothing connecting the two. Nothing. There's a reason LotR is short, and that's because it barely has any characterization and intrigue. You could go one step further and cut away every topographical description and interaction that directly isn't plot-related. By your standards, that should be a better book. Fuck what Tolkien wanted. Not like the guy knew what he was writing down or anything. Nah, it must just be a lack of editing, bruv. Fuck dem trees and shit nigga. Give me a story, amirite?
And this is why these arguments are so pointless. Who are you to decide what goes and what doesn't go into a work? I can think of very few books where it's absolutely clear the author has no idea what he's doing and we're just slogging around filling a quota. And it's impossible to make an argument until the work is completed, at which point you can see if and how everything ties in.
Take the Brienne chapters in AFfC. Many people think they're pointless. They're not, because they're providing a lot of world-building in huge chunks (which is directly relevant to what's to come in the Connington and Aegon part), and giving you a feel of Westeros outside of the capital and after everything that's happened. The only thing you can argue is that Martin should've chosen expediency and simply info-dumped everything in a single chapter, no matter how painful. Which is, again, a matter of taste and principles.
It goes without saying that all of these books could be improved and that there's fat you could trim off. But there isn't nearly as much of it as you think. And making comparisons between ASoIaF and LotR, or making the amount of pages one takes the main criteria for judging a series is fucking dumb.
